Should I use an arduino to control my balancing robot's motors?

I'm building a 2-wheel balancing robot from old parts. DC motors from an old printer, wheels from a BBQ, bodywork from an old optical drive etc. The brain of the robot is a Raspberry Pi 3. I'm using an L298N motor driver to control 2x 12-35v DC…

2DOF arm with quick movement: Stepper, servo, or DC motor?

To make a two degree of freedom arm capable of speeds needed to play air hockey, how should the arm be controlled? I'm wondering about speed vs accuracy. The following image is from a project involving a 2DOF drawing arm: For this air hockey…

How can I implement tremaux algo in arduino line follower to navigate and create map?

The Map1 The task is divided into 2 runs, In first run, We have to navigate through whole map and reach the end mark taking all checkpoints. In second run, using the mapping from first run we have to follow the shortest path. I am reading Algos and…

Harmonic drives in hobby projects

After a fair bit of research into industrial robot arms I've learned that a lot of them use components like harmonic drives and sometimes cycloidal gearboxes. Two main questions: How feasible are these for use in a hobby project? I do have several…

How to invert D-H parameters

I currently have a working kinematic chain made by a set of ten links in D-H convention (with usual parameters [ $A_i, D_i, \alpha_i, \theta_i$]). But my task currently requires the inversion of some of them. Basically, I would have a part of the…

Determining position from a 2D map and LIDAR

We need to determine the 2D position of my robot. To do so, we have a LIDAR at a known high, with an horizontal plane, which gives us the distance to the nearest point for each angular degree (so 360 points for one rotation). The environment is…

Why don't cheap toy robotic arms move smoothly?

Why don't cheap toy robotic arms like this move smoothly? Why can't it even move itself smoothly, (even without any load)? In other words - what do real industrial robotic arms have, that cheap toys don't?

navigation on rugged terrain

I use ROS2/Python/Gazebo. I need navigation (and mapping) for a tractor on a hill: a rugged surface, so to speak. I can of course project everything on a flat map, but distances will shrink and I think localization and path planning will begin…

Will this pseudocode work as a basis for a flight controller?

I'm programming a flight controller on an Arduino. I've researched how other people have written theirs but without notes it's often so obfuscated that I've decided it will be easier and better to write my own. This is my pseudocode thus far, will…

is it possible to get all possible solutions of inverse kinematics of a 6 DOF arm?

I would like to know if there is any way to get all the possible solutions of inverse kinematics of a 6 DOF robotic arm? I have found some good Matlab codes but gives only one solution like in Peter corke's book . Thank you in advance.

Dynamic torque simulation for a 6 DOF robotic arm

I am working on a 6 DOF robotic arm(industrial manipulator). I have the basic structural specs (dimensions, weights etc) for the links and joints with me. Basically, I want to simulate both static torque(Due to the weight of the arm) and dynamic…
